Question 164394


Melanie paints at the rate of 1/x barns per day

Melissa paints at the rate of 1/2x barns per day

Together, they paint at the rate of 1/x + 1/2x =2/2x+1/2x=3/2x barns per day, so in 1 day they paint 3/2x of the barn.

If x=5:
3/2x=3/2*5=3/10 of the barn

Melanie Paints at the rate of 1/x barns per day
if x=5, she paints 1/5 of the barn per day
Melissa paints at the rate of 1/2x barns per day
if x=5, she paints 1/10 of the barn per day
So, 1/5 + 1/10=2/10+1/10=3/10 of the barn

Hope this helps-----ptaylor
